Application filed November 18, 1907. Serial No. 402,688.

To all whom it Be it known that W6,'GUSTAV ELxELEs' and ERNST KLIE, chemists, both subjects of the German Emperor, and residents of 60 Strelitzerstrasse, Berlin, .German Em ire,

have jointly invented a new and useful urniture-Polish and aProcess for Producing Same, of which the following is an exact specification.

The adaptability of shellac for certain industrial purposes is not only due to-the fact that it contains resinous ingredients which produce a glossy varnish or lacquer, but also to the quantities of wax-like material there in. This wax consists principally of cerylalcohol and myricyl-alcohol of which there is nearly 50 per cent. in a free state, the other portion bein bound by stearic, almitic and oleic acid. By dissolving she ac in alcohol and allowing it to stand, the said wax-like substances are separated. But

as is well known, well ada ted for furniture polishing urposes, provi ing the wax-like substance e not taken from it by filtering,-

the same solution assumes at once resinous sticky properties if the wax-like residues are removed and the solution is no longer suitable for polishing. The pad or rubber of the furniture polisher no longer slides easily over the surface of the wood and in fact does not put on the film of olish but rathes takes up parts of the film o polish already put on the wood owin to the sticky properties of this so called po ishingsolution in the absence of the wax. a

Resins from various sources have been 1producing the difierenfi substiapart from .the property of being dissolved in alcohol, laid upon the gloss-giving ingredients alone. Although attempts have been made to increase the e asticity of the shellac- I substitutes by adding fats, OllS and their derivatives, it was found in such processes that the object was not attained b addin a small amount of fats and oleic aclds and t at by increasing the quantity of oil the polish was not glossy but in fact smeared the surface of the wood. Further it has been suggested to form a polish by adding a wax soap to a resin but such saponified wax contains the fatty. acids in an objectionable form which destroys the'polishing action of the wax alcohoL- The presentimprovement consists in the ins employed as shellac substitutes, for

Which purpose quite small additions sufiice. 0111 5 per cent. of a wax alcohol or ester with a high boiling point (or a mixture of both) transforms the previously sticky resin to a finished product which is exceedingly useful for. polishing purposes and acts just like leaf-shellac. Such a mixture maybe made mechanically or the compounding may also be accomplished chemically. In the following is given an example of the latter method. For the production of such a composition, 1 00 grams oftopal with 20 grams of hydrate of sodium are dissolved in 1000 cubic centimeters of water and to the hot resin solution about .5 gram of Chinese .wax isa'dded. The wax begins to melt and is exceedingly finely diffused in the resin solution by means of a rapidly rotating stirring device so as to form an emulsion. If the emul sion of resin andwax be now precipitated b means of a diluted mineral acid, such as s furic acid, the shellac-like finished product is obtained after se arating the precipitate and then washing an drying the separated mass. The preci itate from the'emulslon especially when furt er treated as hereinafter described 5 though clear when being dissolved, se arates the resin into flakes after a few hourst ereby making the product of little value for m- .dustrial aplphcation. This fault is removed by the fo tion, the with the ute mineral acid added in excess, heated up'to 7080 (3., whereupon the filtration follows. A resin thus treated is,

After precipitaafter drying, absolutely solublein alcohol without formingin resin flakes later on. w

Having thus fully described the nature of my invention-what I desire to secureby Letters Patent of the United States is u 1, A polish for furniture and the like composed of an intimate mixture ofresin and a small ercentage of unsaponified wax and an alcoho 'c solvent for said mixture, said polish being characterized by;ai1 exceedingly fine reci itated product is, together and even division of the wax throughout the "solution.

Process or producing a furniture polish, base substance soluble in alcohol comprising dissolving a resin substance together with sodium hydrate in hot water addin a small quantity of unsa onified wax stirring the same violently, precipitating the same by 20 means of an excess of mineral acid heating the precipitate to ether with the excess of acid, filtering, was ing and drying said precipitates.

In witness whereof we have hereunto set 25 our hands 1n the presence of two wltnesses.
